Det här är ju inte rent blått utan också grönt, men jag hoppas det kvalificerar sig till blå måndag hos Emelie ändå. OPI This Color's Making Waves is a beautiful metallic that has a slight duochrome effect, it shifts between blue and green. I don't mind the brushstroke marks at all, in fact I think they add something interesting to this polish. It reminds me of China Glaze Deviantly Daring, but I think This Color's Making Waves is a little lighter in color. The formula is sheer, this is actually four coats. If I had used thicker coats I could probably have gotten away with three. Except for the sheerness, the formula was very nice.
